Abstract (en)
[origin: EP0624552A1] Lithiated manganese oxides are synthesized using a novel two stage process. Using appropriate starting materials, lithiation is accomplished via low temperature ion exchange in aqueous warm salt solution. A heating stage follows which completes the synthesis. Materials suitable for use as cathodes in lithium ion rechargeable batteries have been prepared in this way. Novel materials might also be prepared using a similar low temperature ion exchange process.
